Medical expenses tax deduction - eyeglasses?

So the income tax guide says that you can claim eyeglasses as a medical expense but does not specify if this is the prescription lenses only or if this also includes the frames. Taxtips.ca (LINK) says that this indeed includes the frames.

Last year I bought 2 pairs of frames and lenses. Can any tax experts confirm that I can indeed claim both pairs on my income tax? This kind of seems too good to be true.

You may be able to claim a credit of up to $1,022 if all of the following apply:

You have an amount on line 215 on your return or on line 332 of Schedule 1.
You were resident in Canada throughout 2007.
You were 18 or older at the end of 2007.
In addition, the total of the following two amounts has to be $2,984 or more:

your employment income on lines 101 and line 104 (other than amounts received from a wage-loss replacement plan) minus the amounts on lines 207, 212, 229, and 231 (but if the result is negative, use “0”); and
your net self-employment income (not including losses) from lines 135 to 143.

You cannot claim this credit if the total of your net income on line 236 and your spouse or common-law partner's net income (line 236 of his or her return, or the amount that it would be if he or she filed a return) minus any Universal Child Care Benefit (UCCB) amount reported by you on either line 117 or in the “Information about your spouse or common-law partner” area on page 1 of your return is $43,067 or more.
